Farming for materials is limited with the level requirements: when the monster is 6 or more levels below, the drop rates get significantly worse (proportionally to the level difference).

Farming For Quest Items

There are certain quests lucrative enough to continue doing them even when you don't match the level requirements, since turning in the quest items brings you more Lineage 2 Adena than regular hunting (for comparable periods of time). So, if you don't mind to sacrifice your leveling speed, do it as long as you want and augment your wealth gradually.

The following repeatable quests are worthy of mentioning in this context:

The Grim Collector (level 15-25);
Sweetest Venom (level 18-28);
Coin of Magic (level 40+);
Under the Shadow of the Ivory Tower (level 40+);
Plunder Their Supplies (level 52-60);
Kail's Magic Coin (level 55+);
Whisper Of Dreams (level 56+);
Supplier Of Reagents (level 57+);
Stolen Dignity (level 58+);
Legacy of Insolence (level 59+).

This guide is imcomplete. More Lineage 2 Adena will come soon...
